Try it!!

Slice:Drop is a viewer for medical imaging data. It supports
a variety of scientific file formats out-of-the-box (see here for a complete list).

We think that the best way to render your files is without any
necessary conversions. Just drop'em on a website and they are ready
to render.

Getting started: Just drag'n'drop some medical imaging files
on this website or try one of the four examples in the right
corner. Then, play with the panels on the left and click, drag and
rotate the 3d content.

Slice:Drop uses WebGL and HTML5 Canvas to render the data in
2D and 3D. We use our own open-source toolkit to perform the
rendering, called XTK.
